Grayhill 76MPSB05S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 76MPSB05S is a 5-position DIP switch with SPST (Single Pole Single Throw) circuit configuration, rated for 150mA at 30VDC. This component features a piano-style actuator with raised level, gold-plated copper alloy contacts, and through-hole right-angle mounting. The 76MPSB05S is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and contact specifications to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 76MPSB05S are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires matching of the following parameters:

• Circuit type: SPST configuration
• Position count: 5 positions
• Current and voltage ratings: 150mA at 30VDC
• Actuator style: Piano type with raised level
• Contact specifications: Copper alloy with gold finish
• Mounting configuration: Through-hole, right-angle orientation
• Pitch and dimensional specifications: 0.100" pitch, 0.301" height, 0.580" length
• Operating temperature range: -40°C to 85°C
• Lifecycle ratings: 2,000 mechanical and electrical cycles
• Compliance certifications: ROHS3 compliance and MSL 1 rating

Parts meeting all these criteria are considered direct functional equivalents. Packaging differences alone do not preclude substitution when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB05ST is a direct functional equivalent to the obsolete 76MPSB05S. All electrical parameters, mechanical dimensions, contact specifications, and environmental ratings are identical. The primary distinction is product status: the 76MPSB05S is obsolete while the 76PSB05ST is active, ensuring ongoing availability and manufacturing support.

Both parts carry identical ROHS3 compliance and MSL 1 ratings, confirming equivalent environmental and regulatory standing. The packaging difference (tape seal versus tube) does not affect electrical or mechanical performance and represents a standard variation in component delivery formats.

For new designs or production continuity, the 76PSB05ST should be specified as the primary component. The 76MPSB05ST maintains full compatibility with existing PCB layouts, assembly processes, and circuit designs originally developed for the 76MPSB05S.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB05ST be used as a direct replacement for the 76MPSB05S in existing designs?

A: Yes. The 76PSB05ST is electrically and mechanically identical to the 76MPSB05S across all specified parameters. No circuit modifications or PCB layout changes are required. The substitute part maintains the same pitch, height, mounting orientation, and contact specifications.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 76MPSB05S is classified as obsolete, indicating discontinued manufacturing and limited availability. The 76PSB05ST is active, ensuring reliable supply, ongoing manufacturing support, and compliance with current industry standards. For production applications, the active part is preferred.

Q: Does the packaging difference (Tape Seal vs. Tube) affect compatibility?

A: No. Packaging format does not affect electrical performance, mechanical fit, or functional operation. The difference reflects only the delivery and storage format. Both packaging types contain identical components with identical specifications.

Q: Are the compliance certifications equivalent between these parts?

A: Yes. Both the 76MPSB05S and 76PSB05ST carry identical ROHS3 compliance and MSL 1 (Unlimited) ratings. They meet the same environmental and regulatory requirements.

Q: What parameters must remain identical for substitution to be valid?

A: Circuit configuration (SPST), position count (5), current rating (150mA), voltage rating (30VDC), actuator type (piano, raised), contact material and finish (copper alloy, gold), mounting type (through-hole, right-angle), pitch (0.100"), height (0.301"), length (0.580"), operating temperature range (-40°C to 85°C), and lifecycle ratings (2,000 cycles) must all match. The 76PSB05ST meets all these requirements.
